将整数存储在输入中，与字符分开

Question

基本上，我正在创建一个程序，将 phone 数字转换为中的字母，变成纯数字。我设法做到了这一点，但是，如果您输入数字，它们将被删除并且只有转换后的数字信件被退回。

例如，如果您输入 1800BUYNOW，而不是返回 1800289669，它 returns 只是 289669.

有什么帮助吗？

#phone number converter
#v0.8
#this will convert phone numbers with letters in, into just phone numbers
#i.e. 1800BUYNOW should output as 1800289669

import time
import string

dicti = []

''')
    for char in (num):

            dicti.append(2)

Answer 1

直接替换

   if char in ['A','B','C']:

来自

   if char in ['A','B','C','1']:

等等。

实际上你应该在末尾有一个 else 来报告未知字符并将 if 替换为 elifs。
